Common Nametuberculostearic acid
DescriptionTuberculostearic acid, also known as 10-methyloctadecanoate or 10-methylstearic acid, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. A methyl-branched fatty acid, the structure of which is that of stearic acid carrying a methyl group at C-10. tuberculostearic acid is found in Dicliptera roxburghiana. tuberculostearic acid was first documented in 1987 (PMID: 2885596). Tuberculostearic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 8887930) (PMID: 3329256) (PMID: 14723350) (PMID: 8438134).
